you could play these with pro difficulty - I don't know... they weren't tested on that level. you just enter the numbers - don't worry about anything else. as soon as you change the values they become "custom" sliders.
in the coach profiles you can change a LOT of coaching values... It's under options and coaching profiles. you'll see each coach and a bunch of categories you can change. this is a ROSTER save, and NOT a settings/sliders save. hope this helps...
